Abstract

We propose a conjecture relating two different sets of characters for the complex reflection group G(d,1,n)G(d,1,n). From one side, the characters are afforded by Calogero-Moser cells, a conjectural generalisation of Kazhdan-Lusztig cells for a complex reflection group. From the other side, the characters arise from a level dd irreducible integrable representations of Uq(sl)\mathcal{U}_q(\mathfrak{sl}_{\infty}). We prove this conjecture in some cases: in full generality for G(d,1,2)G(d,1,2) and for generic parameters for G(d,1,n)G(d,1,n).
